in the drawings, 'wherein for the purpose Specification of Letters Patent.

oi illustration is shown a preferredrembodiment of my invention, the numeral l5 des1gnates a casing, which is preferably. formed of sheet metal. This casing is substantially U-shaped 1n' cross-section and its upper surface or 'face is preferably flat. As more clearly shown in Figs. lA and l2, the fiat face or top or' the casing l5 is provided with a longitudinal opening 16, spanned by a section of glass 17, or other transparent ma terial. This glass is held in place by flanges i8, clearly shown in Figs. 7 and 9. Formed upon thel top of the casing `l5 and extending longitudinally along the opening ltr is a scale 19, preferably representing a unit of measure, in this particular instance n, yard. This scale is divided into inches, shown. Arranged inwardly of and near the yard scale 19 is a scale or chart 20, designating the price of the goods to be meas nred, per unit or yard. A correspondingly arranged scale 21. is disposed upon the opposite side or' the opening lf3, and desigthe price oi the goods in smaller units, such as one-eighth of a yard. y

.fis clearlyshown in Fig. 12a, a window 22 is secured to the top ot the casing l5 and has an opening' vWithin this opening are Price per yard indicating the character of the scale 2O and Price per it yard indicating the character of the scale 2l. iVithin the opening 28 can also be seen that portion of a chart, to be described, indicating the number oi yards which have been measured. n

Attached to one end oi' the casing l5 is a iianged cap 22 to which is secured a trameplate 23": showuinore clearly in Figs. 4, 5 and 3. The trame-plate carries posts 2l, rigidly' secured thereto, and a coactingtrame-plate 25 is secured to the opposite ends of the posts 24;.'

As more' clearly shown in Fig. G, a driving shaft, 27 is journaled through openings This driving shaft has a .rotatable element rigidly secured thereto. Outwardly of the rotatable element 29 the driving shait is provided With a screw-threaded portion 30, having screvwthreaded engagement with i the head 3l oi a depending stop 32, to be described. The driving shaft 27 extends through openings and 34:,and is provided exteriorly oi the casing 25 With a hand wheel 3G, rigidly secured thereto. The rotatable element 29 embodies an inner lratchet wheel 37, having its teeth facing Patented Apr. 13, '1920.

with the inner counter-clockwise, as more clearly shown in Fig. 5. This/ rotatable element also comwithout interfering Y with the rotation thereof.

Means are provided to rotate the driving shaft 27 clockwise, comprising an inner reciprocatory element or bar 40, contacting side of the frame-plate 23 This* inner reciprocatory element or bar is free to move vertically but cannot partake of perceptible lateral movements. The

numeral 43 designates an outer reciprocatory element or bar, arranged to contact with the inner side of the inner element or bar 40 and having diagonall arranged slots 44, receiving lugs 45, `whic are rigidly attached to the bar 40. It is thus apparent that upon the downward movement of the bar 43 the same will first move wardly with respect to the bar 40 and when the lugs 45 contact with the upper ends of the slots 44, the two bars 40 and 43 will move downwardly together. When the bar 43 is shifted laterally, as above indicated,

teeth 46 formed upon-one edge thereof are brought into contact with the ratchet Wheel 37, whereby upon further downward movement of the bar 43 this ratchet. wheel is turned for the proper distance. At its lower vend the bar 43 1s provided with a lateral extension' 47, having connection with a retractile coil spring 48, having its upper end attached to the stationary element 49 and serving to move the bar 43 upwardly.

As more clearly shown in Fig. 5, the bar 40 is provided at its lower' end with av shoulder 50, adapted to be engaged b a dog 51, pivoted at 52. This dog is move to the active positidanuby means of a spring 53. The lower end yfthe bar 43 is provided with a cam element 54, which when the bar 43 is l moved'ownwardly for a slight distance and thereto,

shifted laterally, contacts with the upper end of the dog 5l, thereb moving the same from beneath the shoulder 50, and releasing the bar 4@ for downward movement.

As more clearly shown in Figs. 4 and 5, a swinging lever 55 is provided, which is U-shaped in cross-section, for the reception of the upper end of the bar 43. This upper end is beveled, as shown at 56, for contact a transverse element 57, attached to 55 straddles a stationary support or bracket 58, attached to a top plateY 59, and is pivoted as shown at 60.

The backward turning movement of the operating shaft 27 is normally prevented by means of a the ratchet wheel 38. This pawl is pivoted laterally and down- 'screw-threaded engagement therewith.

pawl 61, arranged to engage' at 62 and is provided with a. lever portion .63. At one end, this lever portion carries a button 64, arranged in anopening 65. The opposite endof the lever portion 63 is provided with a flange 66, having connection with a retractile coil s ring 67, attached to one of the posts hen the button -64 is pressed inwardly the pawl 62 is moved out of engagement with the ratchet wheel 38.

The rotatable element 29 is provided outwardly of the ratchet wheel 38 with a brake drum 69, adapted to be engaged/by a brake shoe 70, carried by a reciprocatory rod 71. This reiprocatory iod has its lower portion operating-within a stationary apertured bracket 72 while its upperl portion vextends throu h a slot in theflange 466. A compressile coil spring 73 is arranged between the flange 66 and the brake shoe 70. When the buttonv 64 is pushed inwardly to move the pawl 61 out of engagement with the ratchet wheel 38, the flange 66 will place the spring 73 under tension, thereby shifting the brakeshoe i'nto contact with the drum portion 69, for preventing the operating shaft 27. from rotatin in a reverse. diiection at too high a spee 32 travels toward a disk 76, formed tions.

15 is a plate 78, having a frame-plate 79, rigidly secured thereto, as shown at 80. Spaced from the frame-plate 79 is an inner plate 8l secured thereto by means of posts 82. As more clearly shown in Fig. 12, a shaft 83 has its inner end thereof'rotatable within al1 opening 84 in the plate 81, and a ring 85 rigidly secured to the shaft outwardly ofthe plate 81. Arranged upon the shaft'v 83 is a sleeve 86. The outer end of the shaft 83 is screw-threaded for the reception`of a clamping nut or cap 87 haing L urrounding the sleeve 86 is a spiral s ring 88, one end of which is attached to tiie sleeve 86, and the opposite end of which is secured to one of the posts 82, as shown at 89 in Fig; 3. `Arranged upon the shaft 83 is a large gear 90 disposed between the ring 85 and the inner end of the sleeve 86. When the nut 87 is screwed up, 'he sleeve 86 clamps upon' the rotatable element 29 and this stop ele-' Secured to the-opposite end o'f the casing A iis Laaaeea i smaller geary 91, rigidly attached to a stubshaft'92, rotatable in the frame-plate 81. It is thus apparent that the spring 88 is adapted to rotate ,the gear 91 in a counter-` clockwise directiomwhen the stub-shaft released.

Arranged within the casing 15 and extending longitudinally thereor" in parallel relationis an upper winding roll 93 and a lower take-up roll 94. As more clearly shown in F ig. 6, the shaft 27 has a plug or f member 95 rigidly secured thereto, which projects into one end ot the tubular roll 93, which is clamped to the plug by means o a clamp v96 or other device, whereby the upper roll turns with the plus'. At its opposite end, the upper roll 93 is suitably connected with a stub-shaft 97, rotatable "in the frame plate 81. rlhe lower tubular roll 94 has suitable connection with a stub-shaft 98, see

Fig. 6, which is rotatable in an opening iu the cap 22. At its opposite end the lower roll 94 is rigidly connected with the stubshaft 92.

Suitably connected with the upper Aroll 03 is a iiexible chart 100, provided with vertical and horizontal lines 101 and 102, providing spaces for the reception of' calculations 103, adapted to be arraiiged in cooperative relation to the s e 20. "Cen trally ot the chart 100 is a eoiuinn. 103', in dicating the number of yards or trac-tions thereof, which have been measured and designated No. yards. This coliA in otviigures is apparent within the opening 10 through the opening ofthe window' 22.

Control means are provided for regulating the extent of turning movement of the drivingshaft 27, upon each stroke of the lever 55, comprising a reciprocatory or mov able control element or plate 104,: slnwn more clearly in Figs. and 10. This control plate isprovided upon its upper portion with a plurality oi' steps 105, 10, 107, 108, and 109. The control plate 104 is pivoted at its .lower end, shown at 110, with stationary plate 11.1. The control plate 10-1 is moved to the left in Fig. 3, by a retractile coil spring 112, attached thereto, and to one of Ythe posts 24. When in the normalposition, the uppermost shoulder 105 engages beneath a tooth or lug 118, preferably formed integral with the reriprocatory bar 40, thereby positively limiting the downward movement oi? the bar 40.

As more clearly shown in vFigs. 3 and 10, a reciprocatory rod 114 is pivoted to the reciprocatory control member 104, at 11o. T his reciprccatory rod extends longitudinally within the casing 15 and is guided by apertured brackets 116, formed upon stationary plates 117. The rod 114 has a plu- Cause rality or collars.118, rigidly secured thereto and adapted to contact with the apertured brackets 116 when the rod 114 is movedto the end of its travel in the direction of the arrow. Pivoted to the stationary plates 117 as shown at 119, 120, 121, and 122, are bellcrank levers123, 124, 125, and 126, respecn tively. The lower ends of the vertical arma ot these levers are adapted to contact with the collars 118. The bell-crank lever-128 is so constructed and pivoted that when it is moved downwardly forthe entire extent of its travel it will shift the controlplate 104 to'the right in Fig. 3, sufficiently whereby lthe lug 113 will be positioned above the second shoulder 106; the bell-crank lever 1.24 will shift the rod 1144 sufficient to move the plate 104 so that the lug 113 will contact with the shoulder 107; the bell-crank lever 125 willvshift the plate 104 sutiici'ently to the lug 113 to contact with the shoulder 108; and the bell-crank lever-126 will move the plate 104 sufficiently to cause the lug 113 to Contact with the shoulder 109. The bell-crank levers are actuated by r`eciprocatory pins or plungers 127, 128, 129,

and 130 respectively. Each pin has the y upper portion thereof mounted within an aperture formed in a stationary ear 131 and the lower end of the pin isreduced to forni an extension 132 and a shoulder 133. rl"he reduced extension 132 operates within an aperture i'orn'ied in a stationary ear 134. A. shoulder or ring 135 is rigidly secured to each pin 127 arid is disposed above the horizontal arin of thebelbcrank lever.

As more clearly shown in Fig. 1, the pins extend through openings formed in the top of the casing section., and the pin 127 is located at the nine inch point on the yard scale 10, and is thereby adapted to measure a 7l; yard. The pin' 128 is located* at the eighteen inch point on the yard scale 19 and is therefore a ipted to measure 3 of a yard. T he pin 120 is located at the twentyseven inch point on the yard scale and is therefore adapted to measure ot a'yaid inch point and is therefore adapted to incas ure a yard.

in use, casing 15 is preferably; au. ranged upon .nner side of the shop counter w n' its top thereof liush with the counter [he casing may be secured to the counter ,`bi'aclrets or any other suitable means. ot' the apparatus, it may be assumed that it is desired to Seli yards of cloth at 50c per yard and to ascertain the correct total amount of the sale. arranged upon the counter to the-right of the machine and the operator holds the tree end ot the cloth in the lett hand and brings saine in proximity to the scale '19 to measure a yard, holding the cloth upon the two ends The bolto sloth is downwardly until its cam 54 shifts the shoulder 50. The continued movement of the bar 43 downwardly causes the bar 40 to move withit. `The Al() will move the lug 113 thereof con-v tacts with the shoulder is repeated until 'five yards of cloth are measured. To

measure the half of a yard the goods is placed upon the yard scale 19 and the pin 128 is depressed, and the lever 55 is depressed. The bar 40 will not move down for its entire extent of travel but its downward movement is stopped when the lug 113 contacts with the shoulder 107. The operator now turns to the scale 20, and to the 50 designation. Beneath this designation, in the opening 16, and upon the chart 101 will be found $2.75, the total amount.

When it is desired to rewind the chart, preparatory to a new operation, the operator forces the button 64 inwardly whereby the pawl 61 disengages the ratchet wheel 38 and the spring 88 and associated elements turn the take-up roll 911 counter-clockwise, thereby restoring the parts to the normal position. The movement of the upper roll 93 is, positively limited, when the chart is returned to the proper normal position by the stop 32 traveling to the right, in F ig. 6, and into the path of travel of the tooth 77, which engages .therewit It is to be understood that the form of my invention herewith shown and described is to bei taken as a preferredexample of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub joined claims. l
